Claims

[Scope of Claim for Utility Model Registration] (1) A medical bag in which a polyethylene mouth member is attached to one opening of a polyethylene cylindrical sheet, and the openings at both upper and lower ends are welded and sealed in a flat plate shape. The boundary line between the flat welded part and the intermediate bag formed by these is perpendicular to the center line connecting the widthwise centers of the cylindrical sheet of the upper and lower flat welded parts. A medical bag characterized in that the portion other than the curved portion whose tangent is a straight line is formed by a curved line whose tangent is at an angle to the perpendicular straight line and/or a straight line which has an angle. (2) Claim (1) in which the vicinity of both ends of the boundary line of the lower welded part forms an asymptote with respect to both side edges of the medical bag.
) medical bag. (3) The medical bag according to claim (1) or (2), wherein the upper and lower welded portions have knurled surfaces.
